That is why we are focusing our energy on completely rethinking and re-designing how the new generation of building materials is made. Ecovon are developing sustainably sourced, newly engineered wood made from coconut husk and sugar cane bagasse, supplying the global market with a formaldehyde-free bio-based wood alternative that are better for people and planet. Ecovon will bring the first non-additive, bio-based, renewable wood product to market which is naturally flame retardant and anti-fungal without added binders (glues). The physical properties are better than comparable engineered woods on the market currently, all which use additives and heavy chemicals to reach additional flame retardant properties while reducing our CO2 footprint, deforestation and enriching the lives of locals in coconut and sugarcane producing developing countries such as Ghana. The board material has been shown to exhibit excellent properties, which are comparable with or even superior to commercial wood based panels. Our product is stronger and more durable, priced considerably less, and greener. Coconut husk has the highest lignin content of any known plant and this helps the raw material to bind into a hard board without the addition of any damaging glue or binder. Due to its strength the board has the potential to be used for structural elements in buildings. It also has natural anti-fungal properties and burns three times slower than wood. The method is sustainable and environmentally friendly. The residual material of the coconut is used in its entirety. It is a good alternative to wood and helps to prevent deforestation. During production, glue and chemical agents do not need to be added. Furthermore, the production is CO2 neutral. It is inexpensive. The glue that has to be added when boards based on wood fibre are made contributes to one third of the total production costs. Glue is not required to process coconut husk into board material. It can form an extra source of income for farmers in developing countries
